This is my Xib. I just dragged a UIButton and changed its background color.
I created a semi circle layer using this code
let circlePath = UIBezierPath.init(arcCenter: CGPointMake(mybutton.bounds.size.width / 4, 0), radius: mybutton.bounds.size.height, startAngle: 0.0, endAngle: CGFloat(M_PI), clockwise: true)
let circleShape = CAShapeLayer()
circleShape.path = circlePath.CGPath
mybutton.layer.mask = circleShape
and this is my output.
Its perfect as I want it. But the problem is that this button is clickable outside its rounded area(as per actuall shape of button). I want it to be clickable only as rounded shape.
How can I achieve this ? Thanks.
Create action of signature
- (IBAction)buttonPressed:(id)sender forEvent:(UIEvent*)event{
//your code
}
for your button
Find out touch location using this answer UIButton TouchUpInside Touch Location
Check if that location is contained in your CGPath using
- (IBAction)buttonPressed:(id)sender forEvent:(UIEvent*)event{
//find location point using above answer link
if([button.layer.mask containsPoint: location])
{
//proceed with the code
}
}
it returns a bool if it contains point.
ie if it contains point you can proceed otherwise you can return.
Hope it helps :)
